Anotācija In the near future, deciduous wood may be a real alternative to oil as a raw material for production of chemicals and motor fuel. Now bioethanol is produced mainly by fermenting starch-containing (wheat, corn) and sugar-containing (sugar beat, sugar cane) materials. However, in the very immediate future, the circumstances of these raw materials and the new situation in the oil market will put up the use of biomass for the production of bioethanol and different chemicals such as furfural and acetic acid. Unfortunately, till now, the joint production of bioethanol and furfural had not been possible because of the 40-50% cellulose degradation during the furfural obtaining process. The aimed change in the mechanism of the process has permitted to solve two problems simultaneously, namely, to increase the furfural yield from 50% up to 70% from the theoretically possible one and to diminish 7 times the degree of cellulose destruction in the lignocellulosic residue. Based on the theoretical studies of this process, a new technology including two-step hydrolysis of hardwood may be developed.
